Object e.g. metal bar, position detecting device, has indicator with screen that is transparent in non-indicating condition, and section of screen, which displays information and is opaque in indicating condition

摘要

#CMT# #/CMT# The device has a detector circuit detecting an object (1) hidden behind a surface, where the object is arranged in a housing (11). A current supply and an indicator are electrically connected with the detector circuit, where the indicator comprises a screen (14) that is attached to the housing. The screen is transparent in a non-indicating condition, and a section (141) of the screen displaying information is opaque in an indicating condition. #CMT#USE : #/CMT# Used for detecting a position of an object e.g. wood peg, metal bar, supply line, piping and water pipe. #CMT#ADVANTAGE : #/CMT# The section of the screen displaying the information is opaque in the indicating condition, thus detecting a position of the object in a dark environment without the need for a backlight source or an extra light source. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic design of a device for detecting a position of an object. 1 : Object 11 : Housing 14 : Screen 31 : Wall 141 : Section.
